| 英文摘要 | Exhaustive extraction of analytes in their original chemical forms from samples with complex matrices is a pivotal step for speciation analysis. Herein we propose a pretreatment method for extracting and preconcentrating methylmercury and ethylmercury from coal samples by using KBr - H2SO4/CuSO4 - C6H5CH3 - Na2S2O3 system. The extraction conditions, including the volume of the organic phase and the extraction time, were optimized in detail. Speciation analysis of alkyl-mercuries was carried out by high-performance liquid chromatography online coupled with UV-digestion and cold vapor atomic fluorescence spectrometry. The detection limits were 0.6 ng mL(-1) for methylmercury and 1 ng mL(-1) for ethylmercury, respectively. The recoveries of methylmercury and ethylmercury spiked in a sample were 84% and 82%, respectively. The method was applied successfully to analysis of alkylmercuries in four coal samples collected from northeast China. |
